中文摘要	中蒙俄经济走廊战略地位显著,研究其土地利用格局变化与机理,对亚欧大陆复杂巨系统的生态环境保护和社会经济可持续发展意义重大。本文基于全球土地覆盖遥感数据和实地考察,对自苏联解体及蒙古私有化以来的19922019年,中蒙俄经济走廊土地利用格局及其驱动因素和时空变化规律进行了研究。结果表明:①19922019年,中蒙俄经济走廊土地利用变化活跃,土地转换面积为361954 km~2,主要表现为林地持续下降,建设用地、耕地面积迅速扩张。②中国部分的林地呈现先减后增的趋势,2000年后东北平原北部林地增加显著,灌丛与草地、裸地分别净减少13325 km~2、16632km~2;蒙古国部分的林地、灌丛与草地均呈现先减后增的趋势,而裸地面积先增后减,苏赫巴托尔省、肯特省、东戈壁省和戈壁苏木贝尔省四省交界地带裸地增加明显;俄罗斯部分的林地持续下降,共减少46742 km~2,耕地面积增加8478 km~2,贝加尔湖周边裸地增加41417 km~2;俄蒙边境、色楞格河流域以及中蒙俄铁路沿线地区存在沙漠化风险。③人口、经济、产业结构以及政策等是中蒙俄经济走廊土地利用变化的主要因素。 20102018年,人口密度对转为林地的土地影响最大,其解释力q值为0.2597,GDP总量对转为建设用地、裸地、耕地的影响最大,其解释力q值分别为0.9094、0.2234、0.5518。就三国而言,中国部分主要受人口和经济因素以及退耕还林政策的影响,而蒙古国部分则受私有化后超载过牧及开垦耕地的影响,俄罗斯部分主要是砍伐林地和开垦耕地的影响。本研究结果旨在为中蒙俄经济走廊土地资源可持续利用和管理提供科学依据。
英文摘要	The China-Mongolia-Russia economic corridor has a significant strategic position. Based on global land cover remote sensing data and field investigations, this paper studied the land use pattern, driving factors and spatio- temporal changes of the China- Mongolia- Russia economic corridor from 1992 to 2019 since the disintegration of the Soviet Union and the privatization policy of Mongolia. The results showed that: (1) From 1992 to 2019, the land use change of China-Mongolia-Russia economic corridor was active, and the converted land area was 361953 km~2, which was mainly manifested by the continuous decline of forest land and the rapid expansion of construction land and cultivated land. (2) The forest land in China decreased at first and then increased. After 2000, the forest in the north part of Northeast China Plain increased significantly. The area of shrubland and grassland, and bare land in China decreased by 13325 km~2 and 16632 km~2, respectively. The shrubland and grassland in Mongolia decreased at first and then increased, and the bare land increased at first and then decreased. The turning point was the year 2000. And the bare land in the border area of provinces of Sukhbaatar, Khentii, Dornogovi and Govi- Altai increased significantly. The area of forest land in Russia continued to decline, with a total decrease of 46742 km~2 and the cultivated land increased by 8478 km~2, and the bare land around Lake Baikal increased by 41417 km~2. There was a risk of desertification in the Russian- Mongolian border, Selenge River Basin and areas along the China-Mongolia-Russia railway. (3) Population, economy, industrial structure and policy were the main factors of land use change in China-Mongolia-Russia economic corridor. From 2010 to 2018, the population density had the greatest influence on the land converted to forest land, and the explanatory power of q value was 0.2597. The total GDP had the greatest influence on the conversion to construction land, bare land and cultivated land, and their explanatory power of q value was 0.9094, 0.2234 and 0.5518, respectively. China was mainly affected by demographic and economic factors and the policy of returning farmland to forest land. Mongolia was affected by overgrazing and cultivated land expansion after privatization. Russia was mainly affected by deforestation and cultivated land reclamation. The results can provide a scientific basis for the sustainable utilization and management of land resources in the China- Mongolia-Russia economic corridor.
